I am trying to find out who made this dish, an approximate time period, some history, and maybe even a rough value. It appears to have been dipped in 22k gold on the front and had flowers engraved on the gold dipped surface. There is a hand painted picture, as you can see, of a european couple maybe dating 16-1700s in the middle on the top? Not sure? The bottom has a number stamped into the ceramic of 547 for the number manufactured I would guess and a crown makers mark as you can see in the picture. Any information on this would be much appreciated. Even an idea just from a Gold value would be atleast something. Thank you.
